Free Influencer Marketing Tools: What Brands Can Skip Paying For

Free influencer marketing tools cover the measuring, pricing, drafting and invoicing around a campaign: budget, engagement, rates, contracts, disclosure labels, VAT and ROI. They do not find or book creators, which is the step brands usually pay a subscription for.

This guide maps each free tool to the campaign step it covers, compares the free route with paid software, an agency and a marketplace, and shows where the booking step happens.

Most brands assume they need a paid dashboard before they run a first campaign. The Collabios calculators and generators are free and need no signup, and the influencer marketing tools hub lists most of them by job. If you are weighing influencer marketing tools for small business budgets, our influencer marketing for small business playbook covers the steps around them: picking creators, choosing between gifting and a paid post, and tracking what each one brings in.

The free tools for influencer marketing that matter before you book are five calculators, and the table below maps them to the whole path from budget to booking, including the last column, where each step lands on Collabios.

The five tools for this first half of the path, in the order you would open them:

• Influencer campaign budget calculator. Sizes spend by goal, platform, creator tier and deliverables. For the price points behind each tier, use our influencer pricing guide; the numbers live there rather than on this page.
• Engagement-rate calculator. Works out the engagement rate of an Instagram, TikTok or YouTube profile and returns a fake-follower verdict tuned to the creator's tier. Pair it with our guide to spotting fake influencers.
• Hype calculator. Turns followers, likes and comments into a 0 to 100 score against tier benchmarks. It ranks a shortlist by momentum. It does not detect fake followers, so use it after the engagement check, not instead of it.
• Audience-growth calculator. Projects follower growth over 1 to 24 months from today's count and a monthly growth rate, which helps when you are deciding whether to book a creator early.
• Influencer rate calculator. Benchmarks a rate by creator size and platform, so you open a negotiation with a number. Creators use the same band to avoid underpricing.

Once the budget and the rate are set, you can filter creators by niche, country, platform and price on Collabios and open a profile to read its public per-service rates before you book.

Four free tools handle the paperwork around a booking. The contract and disclosure tools give you a template or wording to read and adapt, which makes it a draft, not legal advice. Nothing applies a disclosure label for you: adding the label your market requires stays the job of the creator and the brand.

• EU disclosure generator. Drafts disclosure wording for a paid or gifted post. Read it against the rule table below, because some labels are not enough on their own.
• Influencer contract generator. Drafts a written collaboration agreement for you to adapt, and to have checked where the stakes justify it.
• EU influencer VAT calculator. Walks through the reverse-charge question for cross-border services between EU member states, so you know what to ask your accountant.
• Invoice generator. Produces a clean invoice for a collaboration fee. Creators use it to bill a brand; brands use it to keep a paper trail.

Three rules show why the drafts matter, and they differ by market:

Once the draft terms are agreed, you can send a custom offer on Collabios with the deliverables and the disclosure wording in the brief, and pay at checkout in euros.

Three free tools cover the end of the loop. The best-time-to-post tool compares published posting-time studies by platform, which is useful when you agree a go-live window in the brief. The earned media value calculator multiplies engagement by a CPM you choose, so the result is an estimate of media value, not revenue, and it moves with the CPM you pick. The influencer marketing ROI calculator takes your spend and revenue and returns ROAS, profit ROI, CPA and break-even.

Use the two together: EMV for a media-value figure a finance team recognises, ROI for whether the spend paid back. Neither proves that the post caused a sale, so keep the inputs honest and note which CPM and which revenue figure you used.

Once a delivery is approved in the order on Collabios, you can feed the live post's numbers into these two calculators and start the next booking on Collabios with your own figures in hand.

Free tools replace the calculation, drafting and invoicing work; they do not find creators, negotiate with them or pay them. The table compares the four routes on those jobs.

Modash prices are the listed prices on its pricing page, read on 28 October 2026, and they change. The Essentials plan allows 300 opened profiles a month. For a wider comparison, see our guide to the best influencer marketing tools and platforms, and for discovery tools specifically our influencer search tool guide. If you are deciding between software and a person, whether you need an influencer marketing consultant makes the same argument about people rather than tools.

Free tools have one honest limit. Enterprise-scale team workflows, meaning shared dashboards, approval chains, role-based permissions and automated reporting across many simultaneous campaigns, are the part a paid campaign-management platform does well. A brand running a handful of campaigns with one or two people sits well below that line.

If the only reason you were considering a subscription is to find and book creators, Collabios has no subscription: you search creators on Collabios, book, and pay per collaboration, with the service fee shown before checkout.

Creators get the same tools from the other side of the deal. The rate calculator gives a number to quote instead of a guess, and our guide on setting your rates as an influencer builds the reasoning behind it. The engagement-rate calculator lets you lead a pitch with real engagement instead of raw follower count. The invoice and disclosure generators handle the two admin jobs creators most often get wrong. These free influencer tools work the same whichever side opens them.

Creators can put them to work on real briefs by listing a profile on Collabios, where brands filter by niche, country and price.

The path from a finished budget to a delivered post has five steps on Collabios:

1. Search with filters. Filter by niche, country, city, platform, follower count and price.
2. Read the profile. Each profile shows public per-service rates and content samples.
3. Send the booking. Buy a creator's package or send a custom offer, with a brief covering tone, visual references, deadline and the disclosure wording the creator's market requires.
4. Pay at checkout. Your card is charged in euros and the payment is held through Stripe Connect. The creator has 72 hours to accept; if they decline or do not answer, you are refunded in full.
5. Review the delivery. Approve it, ask for a revision or open a dispute. If you do not respond, the delivery is approved automatically 7 days after submission.

The detail of each step is on the how Collabios works page, and our guide on how to hire influencers covers the decisions around it.

If you already have a figure from the budget calculator and a benchmark from the rate calculator, the next step is to search Collabios for creators in your niche and country, read their public rates, and send a booking request or a custom offer with your brief. Brands from any country can book creators based in Europe, and you are refunded in full if a creator declines.
